Contender, named in honor of OCEARCH partner Contender Boats, is the largest male white shark the group has ever caught, tagged and released in the Western North Atlantic Ocean. The adult shark is 13.8 feet long, and weighs an estimated 1,653 pounds, OCEARCH said. On social media, the organization referred to him as a "true ocean giant."

Researchers are tracking what is believed to be the largest shark ever tagged by OCEARCH in the southwest Atlantic, with its last pings off Florida’s east coast.
